[RESOLVED] Creating an Array

DaemonProjects

Hello,

I have a php script that uses sockets and outputs everything to the console. This is a command line application. I am trying to grab some strings from the output and put it into an array. Now The explode function works but it doesn't place the strings in the right place. I am trying to make it so I can update the array later and make sure its all in order.

example output:

You just logged on line 1 from: localhost
Your name is now: NakenBot
COMMAND FOUND! EXECUTING
[1]NakenBot logged in and systems up!
@
+[0]Derrick
+[1]NakenBot

as you can see above, I want to capture the names after the @. the + means that they are online and the name has not changed. When the name has a - in front of it, that means either the name has changed or they have left the chat. It would be easier if the script detected the - to redo the whole array with the +.

I have a explode function but it isn't what I want. I would like to have the array numbers match the number next to the name. I also need to figure out how to search the array with a wild card. It would be really nice if I could have it the following:

array => 0 => Derrick
array => 1 => NakenBot

then I could search for the number or the name and be able to output them both

hope this makes sense

So are each of these names on a separate line?

E.g., does your script read data in line-by-line? If so, once you detect an '@' has been sent, read the data in line-by-line and do something like this:

// assuming the current line is held in $data

if(preg_match('/^[+-]\[([0-9]+)\](.*)$/', $data, $matches))
    if($data[0] == '+')
        $names[$matches[1]] = $matches[2];
    else
        unset($names[$matches[1]]);

That adds a name to $names if the first character is a + or unsets the corresponding ID from the array if the first character is a -.

I get this now:
Array
(
[0] => Derrick
[1] => NakenBot
)

which is what I wanted, thank you

is there a way I can echo or print all the names with out the numbers like:

Derrick, NakenBot

then if I search for the name or the number I can get that key?

You're probably using print_r() to print, and that is useful when debugging, but normally you would loop over the array to print it, or in this case you can use [man]implode/man.

Use [man]array_search/man.

Use [man]array_search/man.

hey thanks, the implode worked, now going to try the search

DaemonProjects

will the search works now but is there a way I can search partial part of the array

// is user online
if (trim(substr($get_command, 0, 7)) == "!online") {
echo " COMMAND FOUND! EXECUTING \n";
$usernme = trim(str_replace("!online", "", $get_command));
$key = array_search($usernme, $names);
if ($key) {
$key = "User is online!";
} else {
$key = "User was not found!";
}
fputs($fp, trim($key)." \n");
fflush($fp);
}

example:

if there is [1]Derrick

can I search for Derrick or just the number and it will find it? Right now it has to be the exact string 🙁

I believe you have to search manually in that case, e.g.,

// ...
$text = 'User was not found!';
foreach ($names as $name) {
    if (strpos($name, $usernme) !== false) {
        $text = 'User is online!';
        break;
    }
}

fputs($fp, $text . " \n");
// ...

By the way, it would probably be better for clarity to use $username instead of $usernme.
